Application filo'l April 26,l905i Serial No. 257,470.

. iiliddlcsex, England, have invented new and useful improvements in Radiators, tatcaunloiulensers, and the lube, oi which the follownw is a s medication.

The invention has ier its object improvcmeet on that class I radiator, steam--condenser, and the like described in the specification of United States Letters lfatcut No. 713,776, dated November 18, I902, and relates to an improved. construction of grilled llat tubes to be used therein, to headers for lilling the spaces between. the flat tubes at the top and bottom thcreot to form a continuous surface to which the upper and lower parts of the tank can be sweated or soldered, and to a 'lillingcap serving as a safetywalve to permit escape of steam from the radiator in the event of undue pressure arising therein, and thus prevent injury thereto.

1 will describe the invention by the aid of the acconn'ianying drawings, in which- .l igure 1 is a front view of parts of the i1n )IUVGd radiator, steam LZOIILlQHSlEEI, or the like. Fig. 2 is an end View of one of the iniproved flat tubes before the gills are applied thereto. Fig. 3 is an endview of the two parts used in the formation of these tubes. Fig. 4 is an end view of the parts shown in Fig. 3 when assembled and partially closed down to form the tube. Fig. 5 is a plan of a strip of sheet metal stamped to the form preferred to produce, when properly bout, the iin-- proved gills. l igs. (i and 7 are side views drawn at right angles to each other, and Fig. 8 is a crosssection of said stamped-metal sheet bent into the form required. Fig. 2) is a side View, and Fig. 10 is a cross'section, of one of the headers Fig. it) is a cross-scction ofanother form of header. Fig. l I is an elevation of parts of a few of the [lat tubeswith the gills and headers. Fig. 12 is a hor1 zontal section drawn on line l2 12 of l ig. l l, and. Fig, 13 is a side elevation of Fig. 11. Fig. 14 is an under side view, and Fig. 15 is a cross-section, of the improved lillingwap; and Fig. 16 is a plan of the filling tube or nozzle.

In all the figures like parts are indicated by similar letters of reference.

a a. are the flat tubes. 1) b are the upper and lower parts of the tank with which the ends of said tubes coninuniicate. r c are grills or radiatirur surfaces .siohlercd to said tubes.

The flat tubes a are each constructed of two rectangular pieces of sheet nietal a" a",

each of its long sides bent over toward the main body thereof, and the piece it having a portion atalong each of its long sh bent first over toward the main body thereof and then outward, thus forming; an outwardly-- open groove an, into which the part a is 'ilaced, as shown at Fig. l, which figure rep: sin e the parts partially pressed together. i l hen the parts are completely closed down, as shown at Fig. 2, the long edges are sweatcd or soldered to insure herniiticity. l ly these means a solid edge is obtained at both back and front, thus seeming great strength and durability, it being impossible to injure said edges by either blows or friction.

'lhe gills or radiating surfaces c are formed from a stamping c of sheet metal, such as that shown at Fig. 5, having; preferably scr rated [hinges c and apertures c. This stan ing is bent on the lines c to produce the trough-shaped form shown at lfigzs. ti, ain'l S, with outwardly-extending serrated thinner-s 0 by which the same may be soldered across the sides of the flat tubes a and preferably alternately on opposite sides tl'iereui.

By the above construction of gills or radi ating surfaces and their arrangement in the .manner shown the air entering the spaces c and all can by passing through the apertures 0 travel in every direction vertically toward the center oi the fan, thus housing the air passing between the outer flat tubes (1 -that is, away from the con tor of the radiator--to have a greater cooling off .et than if it passed through the spaces c" and r1 without being able to pass from one to the other of said spaces if desired, the flanges 0' may be of other form than that shown, or they may be plain, and the apertures 1- may also be of other form.

c c are headers or filling-in pieces which are placed between the top and bottom ends of the llat tubes a, to the sides of which they are soldered or sweatod, and thus form a continuous llatsnrlacc, to which the top and lmttoni portions 1) ll of the tank are soldered. 'lhcse headers or lillingdn pieces are in the shape of a trough closed at bol h ends.

.ltadia-tors for ureter-isn't; have usually a les the piece a having, a'narrow portion it alone,

horizontal top portion between. the two siering end portions. (Shown at Fig. 1.) The header shown at Figs. 9 and 10 is suitable for use between the tubes, the tops and bottoms of which are in horizontal lines, vvnile that shown at Fig. 10 is suitable for use along the inclined ends.

f is the filling tube or nozzle. it is formed with an inwardly-projccting annular rim 7, in which notches fi are formed.

' g is the improved fillingcap. g g are springs located in chambers or spaces in said cap, and g represents bells against which the outer ends-oi the s rings g beer. Apertures are made in the cy indrical part of the fillingcap, which allow the balls 9 to protrude a certain distance, but not to pass altogether thcrethrough. l/Vhen the filling-can g is in position in the filling-tube or nozz e the springs g force the balls 9 underneath the flange or rim. f thus forming spring-bolts, which secfrely retain the cap 9 in position. If, however, pressure should unduly increase vithin the radiator or the like, the cap will be slightly lifted, thus exposing the upper ends of the notches '1 to the open air and permitting escape of steam until the pressure is suitably reduced, thus preventing injury to the radiator.

h is the ordinary filling-tube filter, and 'i a space to receive the ordinary vent or blow-oi tube or overflow-pipe, should such. be desired.

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed I declare that what I cleim is 1. in radiators, steam-condensers and the like, the combination oi a tank-body, lint tubes communicating between the upper and lower portions of said body, trough-shaped gills or radiating surfaces formed of sheet metal, apertures in said gills or radiating surfaces and outwardly-extending flanges by which the gills or radiating surfaces are seldered between the tubes substantially as set forth.

2. In a radiator, steam-condenser and-the like the combination of a tank-body, liat tubes communicating hetween the upper and lower portions of said tank-body and headers v or filling-in. pieces placed between the ilat tubes at top and bottom thereof to form con tinuous plain surfaces to which the upper and lower parts of the tanir can be readily soldered substantially as forth.

8. In a radiator, stean'i-condenser and the like the combination of e filling-cap provided with spring-bolts, and a filling tube or nozzle having a notched in ar-zllyprojecting rim under which the spring-bolts pressed thus securing the filling-cap normally in position but allowing it to he raised by undue pressure and thereby give vent to the steam through the notches in the rim and so prevent injury to the radiator substantially as herein set in Witness Where-0t 1 have hereunto set my hand in presence of two Witnesses.
